Mosquitopia

The surveillance and detection of zoonotic pathogens in animals is essential for predicting disease transmission pathways and the risks of spillover, but challenges include the costs, ethics and technical expertise required for vertebrate trapping, serum sampling and antibody or virus screening. Surveillance using haematophagous arthropods as a sampling tool offers a unique opportunity to obtain blood samples from a wide range of vertebrate species, allowing the study of host-mosquito associations, and host exposure to pathogens. We explored vertebrate diversity and potential Ross River virus (RRV) transmission pathways by analysing blood-fed mosquitoes collected in Brisbane, Australia. Host origins were identified using barcode sequencing, and host exposure to RRV was assessed using a modified plaque reduction neutralisation test. In total, 480 blood-fed mosquitoes were collected between February 2021 and May 2022. The host origins of 346 (72%) bloodmeals were identified, with humans (73%) and cattle (9%) comprising the dominant hosts. RRV seroprevalence was high in both vertebrate species with evidence of RRV exposure in 70% (21/30) of cattle and 52% (132/253) of humans. This is a novel, non-invasive method of estimating seroprevalence in vertebrate host populations. Our results highlight the potential of blood-fed mosquitoes to provide species-specific insights into pathogen transmission dynamics.

The essay maps and reflects on some dimensions of humanmosquito interaction in the context of the Arctic and inspired by fieldwork in Finnish Lapland. Rather than developing any particular argument, we seek to document this thinking mosquito as a collection of glimpses, fragments and musings. This impressionistic approach was inspired by conversations among the authors and with environmental humanities scholarship about the roles non-humans play in human worlds, and about how one might engage with mosquitos in thinking about scientific fieldwork, about everyday life in various environments, and about the Arctic more generally. The essay does not provide answers but rather questions, hoping as it does to offer some insights into the complexity of issues that connect mosquito worlds to human worlds. As a mirror to these reflections, we dialogue with excerpts from our own creative written thoughts from the field and from the diaries of German soldiers based in Lapland during the Second World War.
